Taiwan Semiconductor Corporation SK810C V7G

Overview

SK810C V7G from Taiwan Semiconductor is a single-die, 8A, 100V Schottky barrier rectifier in DO-214AB (SMC) package, optimized for high-efficiency switching mode power supplies and DC-DC converters where low forward voltage and high surge capability are critical. It features 0.90V max VF at 8A/25°C, 150A IFSM, 10,000 V/µs dV/dt rating, and operates up to 150°C junction temperature.

For engineers reviewing the SK810C V7G datasheet, SK810C V7G pinout, SK810C V7G application, or SK810C V7G equivalent, key selection factors include its 100V VRRM rating, thermal resistance of 20°C/W, moisture sensitivity level 1 compliance, RoHS/halogen-free status, and cathode-band polarity marking - all essential for industrial adapter and lighting converter designs.

Technical Context

This Schottky rectifier uses a planar guard-ring structure to enhance overvoltage ruggedness and suppress leakage under high reverse bias. Its single-die construction and matte tin-plated leads support automated SMT placement and J-STD-002 solderability.

The device delivers stable performance across -55°C to +150°C operating range with 10mA max IR at 100V/100°C, enabling reliable operation in thermally constrained converter topologies without forced cooling.

FAQ

What is the maximum junction temperature rating for SK810C V7G?

The SK810C V7G has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table in the official TSC datasheet L2102. This rating allows uninterrupted operation in sealed enclosures or high-ambient environments without derating up to 100°C board temperature. The SK810C V7G maintains stable reverse leakage and forward voltage characteristics within this range, supporting long-term reliability in industrial LED drivers and telecom power supplies.

Does SK810C V7G have a guard ring structure, and what benefit does it provide?

Yes, SK810C V7G incorporates a guard ring for overvoltage protection, explicitly stated in the FEATURES section of the TSC datasheet. This structure enhances edge termination robustness, raising the critical rate of rise of off-state voltage (dV/dt) to 10,000 V/µs. In practice, this prevents spurious conduction during fast-switching transients in LLC resonant converters or high-frequency flybacks, improving system immunity without external snubbers.

Is SK810C V7G RoHS and halogen-free compliant?

Yes, SK810C V7G is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the FEATURES section of the TSC datasheet. The device uses halogen-free molding compound and lead finish, satisfying environmental requirements for export to EU, Japan, and China. No additional material declarations or exemptions are required for standard use cases, simplifying compliance documentation for OEMs building certified end products.

What is the moisture sensitivity level (MSL) of SK810C V7G, and how does it affect assembly?

SK810C V7G has moisture sensitivity level 1 (MSL1), per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to reflow. This eliminates pre-reflow bake cycles, reduces floor-life tracking overhead, and lowers risk of popcorning during lead-free reflow. For SK810C V7G, MSL1 directly supports high-throughput SMT lines with zero process interruption - a key advantage over MSL2 or MSL3 alternatives.

What is the forward voltage specification for SK810C V7G at rated current and temperature?

The forward voltage (VF) of SK810C V7G is 0.90 V maximum at IF = 8 A and TJ = 25°C, per ELECTRICAL SPECIFICATIONS table in the TSC datasheet. At 100°C junction temperature, VF drops to approximately 0.78 V due to negative temperature coefficient. This low VF reduces conduction losses by ~1.2W compared to standard silicon rectifiers, directly improving efficiency in 60–100W SMPS designs using SK810C V7G.
